BEARING FOR CENTRIFUGAL MACHINES.

v Specification of Letters Patent Application filed August 24, 1912. SerialNo. 716,887.

To all whom it may concern: I

Be it known that I, ERNST LoMMA'rzsc a subject of the Emperor of Germany an'cl resident of Eythra, near Leipzig, Germany, have invented certain new Improvements in Bearings for Centrifugal Machines, of which the following is a specifi cation.

The present invention relates to a centrifugal machine of the kind in which the masses rotate about a horizontal axis, its object being to reduce friction and insure smooth running, thereby reducing the expenditure of driving power as well as removing the main causes of breakage.

According to the invention thehorizontally rotated shaft has at each end a roller 'by means of which it is supported on the T1111 of a wheel the axis of which is arranged in the same perpendicular plane as that of the shaft, the wheel beingitself mounted on a ball-bearing.

running being thus insured. It is evident that the shaft, and the masses connected,

thereto, will, when supported in bearings of this description, move with minimum friction.

In the accompanying drawings the invention is illustrated, Figure 1 representing a front view of the bearing, Fig. 2, a plan, and Fig. 3, a side view of the same. Figs. 4 and 5 are detailed views of the levers and their ball-bearings. Fig. 6 is a plan of the whole machine, the centrifugal cylinder be-,

ing shown partly in section.

The rotating masses are carried by a shaft The shaft is supported by means of this roller on the rim of a wheel owhich is mounted, through themedium of a ball-bearing, on a stud d connected to the This wheel, which is con-' siderably larger than the roller and which leverage.

the same perpendicular plane asthe shaft.

a. Since the forces acting on the shaft are mainly directed downward it isevident that said shaft will be almost exclusively supported on the wheel, and since the latter, being much larger than the roller, moves slowly and easily about its ball-bearing,

"very little friction will ensue.

For holding the shaft on the wheel and supporting any laterally or upwardly directed force, ball-bearings f are provided. These bearings embrace the shaft and each one is held by a single-armed lever e, such levers being pivotedi at g to brackets secured to the machine frame. The free end of each vertical rod on which it is guided, and a spring h is arranged on said rodso as to abut agamst the lever and pressthe shaft against the wheels 0. V The pressure of the springs is adjusted in conformity with the Irrespective of the wear of" the different elements, therefore, the shaft will always be held by the levers steadily against the supporting wheel. Vibrations of the shaft are thus effectively prevented and a smooth runninginsured. Upwardly directed forces, will be supported by the.

springs h and laterally directed forces by the pivots g of the levers. In the case of small machines it will be sufiicient to arrange one ball-bearing f at each end of the shaft; for larger machines it is advisable to employ two ball-bearings at each end, pivoted at opposite sides of the shaft, as shown in the figures. Since the forces acting on the shaft are, as previously notlced, mainly directed downward, there will be but little pressure for the bearings f to support so that excessive wear of thesame is excluded.

I claim?- 1.A bearing for centrifugal machines with horizontally rotating shaft, comprising a wheel mounted on a ball-bearing, a roller firmly connected to the end of the shaft so as to supportthe latter on the rim of said wheel, ball-bearings embracing the shaft near the roller and carried by single-armed with horizontally arranged shaft, coinpris- Wheel, substantially as and for the purpose l0 ing a Wheel mounted on a ball-bearing and set forth.
